Needed a different water pattern..

After using straight cut down stems for who knows how long I wanted to try something different. I learned about "showerhead" down stems and came across Alex K and lo and behold Aqualabs carried them! It works wonderfully and is a semi-ash catcher too!

Alex K Down Stem

This has been my first diffusing downstem and it’s been amazing. Much better filtration over a stranded stem and allows for bigger smoother hits. With that being said there are much better stems out there for not too much more money. Make sure you measure correctly for your piece

Alex k downstem

Great diffusion and the slits are large enough so it doesn’t get clogged easily. I just prefer slightly smaller slits for more restriction.
